                            Chalcopyrite flotation separation is the most widely used method for copper extraction from sulfide ores. Optimizing chalcopyrite flotation can significantly improve copper recovery, increase concentrate grade, and reduce operating costs. Chalcopyrite (CuFeS\u2082) is the most important copper-bearing mineral in the world. Efficient flotation of chalcopyrite requires proper grinding size, suitable
